DO NOT START WITH ORAL SEX ! Especially U have no exp in this whole thing . first u have to practise foreplay several times , get into the intercourse level (if u don't mind dat , or it feels dat he is the ryt one for dis whole new exp ) . later on u can start to consider oral sex the next level of intimacy . Though ur concerns are true . his semen can make u sick , if he has hidden sickness , but if he is healthy and clean takes good care of himself . and u both hit dat level of intimacy already go for it , otherwise it would seem and feel so gross at first time ! :)
Thankyou for good advice.Meanwhile I am practicing achieving orgasms with self pleasuring, O have now learned that this is healthy and actually good for health. My generation was taught so wrongly that sex was immoral etc. I am scheduling therapy for my further improvement invpsychosexual development. Like I am 66 going on 16.
